explain_ic...ose_or_die(3)

💖 NAME 💖

bestie, this is explain_iconv_close_or_die — it deallocates a conversion descriptor, and if that goes sideways it tells you and then, uh, ends the whole program. no cap.

✨ SYNOPSIS ✨

#include <libexplain/iconv_close.h>
void explain_iconv_close_or_die(iconv_t cd);
int explain_iconv_close_on_error(iconv_t cd);

---

🌸 DESCRIPTION 🌸

okay so there are two of them and they're siblings, not twins, and the difference matters, so listen up 🫶

The explain_iconv_close_or_die function is the one that calls the iconv_close(3) system call for you. If it fails, an explanation gets printed to stderr — and that explanation comes straight from the explain_iconv_close(3) function — and then the process terminates by calling exit(EXIT_FAILURE). yeah. it's giving "we die on this hill". 💀

The explain_iconv_close_on_error function also calls the iconv_close(3) system call, and on failure it also prints an explanation to stderr, also obtained from the explain_iconv_close(3) function — but then it still returns to the caller. no dramatic exit, she simply comes back. 💅

• cd — the cd, exactly as to be passed to the iconv_close(3) system call.

---

⭐ RETURN VALUE ⭐

The explain_iconv_close_or_die function only returns on success — see iconv_close(3) for more information. On failure, it prints an explanation and exits, it does not return. like, at all. gone. 🦋

The explain_iconv_close_on_error function always returns the value return by the wrapped iconv_close(3) system call.

---

🎀 EXAMPLE 🎀

The explain_iconv_close_or_die function is intended to be used in a fashion similar to the following example:

explain_iconv_close_or_die(cd);
